python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens

A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

Security Bulletin: IBM Cloud Pak for Data System (CPDS 1.0) is affected by insufficient verification of data authenticity in PyJWT

Summary IBM Cloud Pak for Data System CPDS 1.0 uses the PyJWT library, a JSON Web Token implementation in Python. CVE-2026-32597 affects PyJWT's validation of the crit Critical Header Parameter as defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that PyJWT do...

GHSA-W7VC-732C-9M39 PyJWT: Unauthenticated DoS via unbounded Base64URL decoding of unused payload segment in b64=false detached JWS

!NOTE Practical impact depends on whether request body-size limits are enforced upstream proxy/web-server/framework. Deployments with typical body-size caps ≤2 MB bound the amplifier significantly; deployments accepting larger token inputs are more exposed. When verifying detached JWS tokens usin...

PyJWT: Algorithm allow-list bypass when decoding with `PyJWK` / `PyJWKClient` keys

!NOTE Scored assuming a deployment where algorithm policy functions as an authentication/authorization boundary. In deployments where the algorithm policy enforces crypto agility only, the practical confidentiality impact is lower and the issue is closer to an integrity-of-policy-enforcement bug...

CVE-2026-48523

A flaw was found in PyJWT, a Python library for handling JSON Web Tokens JWT. An attacker with control over a registered JSON Web Key JWK private key can bypass security checks by signing a token with a forbidden algorithm while claiming to use an allowed one. This allows the attacker to have the...
